Been running the HIgh Capacity GFO for two years in two different tanks. On my 90gal. I have the BRS dual reactor with GFO and Carbon. Since running the HIgh Capacity GFO, my phosphate levels are non existant.

Easy and efficient!By Tonyon 2/26/2015

Using with a mix of Rox carbon in my Deluxe BRS reactor and ran clear almost instantly!

Great product, but a bit $$By Submergeon 2/4/2015

You get what you pay for. This GFO works well in a bag in the sump. It doesn't clump if kept in a high flow area. I just massage it around every few days for "general principle". It does a great job at keeping the phosphates low, about 1/10 of what they were before.

Amazing product!By Davidon 1/14/2015

I was continuing to have issues getting my Phosphates down to a negligible amount. I was dosing all sorts of products in an attempt to get the counts down. I installed a BRS Reactor with High Capacity GFO and crossed my fingers. I installed it three days ago and today my reading was 0.05! I can't say enough positive things about this product. Thank you BRS!

I'm sold, will never run without it.By Bruceon 12/14/2014

Was having phosphate issues on my 90g mixed reef tank so I thought I'd give it a try after reading the other reviews....they were right! I am running a BRS single reactor and mix about 1 part High Capacity GFO & 2 parts BRS Premium ROX Carbon. After a week I was convinced my Hanna Checker was broken because it kept coming up 0 phosphates...there was nothing wrong with my Hanna. Been using this about 6 months now and have had no phosphate issues or no ill side effects. I didn't think I really needed the carbon but carbon is cheap and has it's benefits, and with the mix you don't have the hassle of tweaking the flow to try to maintain the right amount of tumble.

after 2months battle with algae, system running with algae scrubber, refugium, large protein skimmer, with all that running I decided to install and use this product, never thought it would work but after 5 days came back from vacation things really improved and all my sps corals starting to look happy and fish get to eat a little more food.
Thank you BRS!

I have used several different types of GFO products and this one gives us the best performance vs cost

This is the only GFO that I use, it keeps my phosphates levels low to nothing. I use it with BRS media reactor with out issues. Great product would recommend it to any one needing g to remove phosphate in their systems
